Unsp fx shaft of l rad, subs for opn fx type I/2 w nonunion

This code signifies a persistent lack of healing (nonunion) of an unspecified fracture located in the shaft of the left radius. It indicates that the initial injury was an open fracture, specifically classified as Type I or II, and the patient is now in a subsequent phase of care for this complication.

Apply this code when documenting a patient encounter where the primary issue is the nonunion of a previously sustained open fracture (Gustilo-Anderson Type I or II) of the left radial shaft. This is appropriate for follow-up visits, surgical interventions for nonunion, or other management related to the failure of the bone to heal.

• Ensure documentation clearly specifies "nonunion" and the left radius shaft.
• Verify the initial fracture was indeed an open fracture Type I or II.
• This code is for subsequent encounters, not the initial treatment of the fracture.
